Actually I would say that, but only if he wanted to deal with the Type R...noise, theft, cost...theft...Since he wasn't asking about R's though....
I guess it depends on whats better for his needs but if hes asking the question between LS and GSR, I automatically assume he can afford the GSR, and that he probably wants to go faster....so I can't see any reason to not go with the GSR besides the extra costs.
